For samples less vibration fault OLTC single feature extraction, feature fusion and proposed IPSO-KNN-load tap changer wherein a mechanical fault points selection method.
In view of the small sample of OLTC vibration fault and the single method of feature extraction, this paper proposes the method of multi-feature fusion and the mechanical fault selection method of the on-load tap switch of IPSO-KNN.
In view of the few samples of OLTC vibration fault and the single feature extraction method, this paper proposes a feature selection method based on multi feature fusion and ipso-knn.
